Houdini 1.5a gets it too: 4/14 00:00 2k 0 -1,68 h4-h5 Kh7-h8 h5xg6 Nf7-g5 Nb4xc6 Qd7xc6 Ra5xb5 5/14 00:00 2k 0 -1,68 h4-h5 Kh7-h8 h5xg6 Nf7-g5 Nb4xc6 Qd7xc6 Ra5xb5 6/18 00:00 4k 3.632k -1,64 h4-h5 Kh7-h8 h5xg6 Nf7-g5 Nb4xc6 Qd7xc6 Ra5-a7 Rb8-a8 7/18 00:00 6k 820k -1,76 h4-h5 Kh7-h8 h5xg6 Nf7-g5 Nb4-...

Re: question about weak level of engines
I prefer the weak levels to have the following properties: 1)They are not deterministic so humans cannot learn a fixed way to beat them. 2)Their playing strength is fixed and not dependent on hardware or time control. Are there engines with weak levels that have these properties when the levels are...

Re: My failed attempt to change TCEC NN clone rules
Quote from the TCEC rules: Definition: A neural network is a computer system modeled on the human brain and nervous system. For the purpose of TCEC a participant is considered a neural network (NN) engine if it generally requires the use of GPU and consists of at least the following 3 parts: The cod...

Re: Similarity tester - 2nd generation - BETA
My impression - not sure if that's true or not, so I'd like to see it tested - is that SF10's play is more similar to LC0 than e.g. SF9 was. That would make sense because if LC0's style is the "chess truth", devoid of preconceptions, one would expect AB engines to gradually approach it. not necessa...

Re: Similarity tester - 2nd generation - BETA
Did some Lc0 testing - http://rebel13.nl/html/kai.html SF vs Lc0 very low similarity. Indeed, and that's not surprising. No real difference between SF8 and SF10 vs NNs - that seems to prove my impression was not correct, though. And, finally, of all AB engines SF is the most similar to Lc0 (while r...

Re: Similarity tester - 2nd generation - BETA
Would be interesting to compare leela (with different networks) to all the other usual AB engines My impression - not sure if that's true or not, so I'd like to see it tested - is that SF10's play is more similar to LC0 than e.g. SF9 was. That would make sense because if LC0's style is the "chess t...

Re: New results in the ERET chess test
Looks like a lottery. Quite the contrary: the list appears to be remarkably well-corelated with playing strength. The above-mentioned German-language article says "surprisingly accurate" ( überraschend genau ), and personally I cannot but agree. Frankly, I thought such tests are outdated now, but c...

Re: Lc0 GPU load
If I try to host the GPU out of the box using a raiser card adopter something like shown below, will it affect the performance? The idea is to give the gpu more cooler air to breath & to cool down. Additional case fans may be a better solution. It is basically the same idea: help the GPU fan by not...

Re: Knight equals 48 pawns?
I downloaded the latest Lc0 about a week ago on my laptop (with GPU 1060), and looked at its analysis (infinite mode) on lots of positions. Typically, in the opening evals are roughly double what they should be; in general a clean pawn up shows as about two pawns. However, the initial position with...
